Aging men aren’t just battling time—they’re up against rising blood sugar. New research reveals that subtle increases in metabolic markers like glucose have more influence on declining sexual health than age or testosterone levels alone. The findings, based on a 6-year study of otherwise healthy men, show that even below-diabetes-level sugar changes can impair sperm …

Postmenopausal women struggling with weight loss may find a powerful solution by combining the diabetes drug tirzepatide with menopause hormone therapy. A Mayo Clinic study revealed that this dual treatment led to significantly greater weight loss than tirzepatide alone. Women using both treatments lost 17% of their body weight on average, compared to 14% in …

Movement helps your mood, but it’s not one-size-fits-all. Exercising for fun, with friends, or in enjoyable settings brings greater mental health benefits than simply moving for chores or obligations. Researchers emphasize that context — who you’re with, why you’re exercising, and even the weather — can make or break the mood-boosting effects. ​Movement helps your …

In the frozen reaches of the planet—glaciers, mountaintops, and icy groundwater—scientists have uncovered strange light-sensitive molecules in tiny microbes. These “cryorhodopsins” can respond to light in ways that might let researchers turn brain cells on and off like switches. Some even glow blue, a rare and useful trait for medical applications. These molecules may help …

Scientists at the University of Sydney have uncovered a malfunctioning version of the SOD1 protein that clumps inside brain cells and fuels Parkinson’s disease. In mouse models, restoring the protein’s function with a targeted copper supplement dramatically rescued movement, hinting at a future therapy that could slow or halt the disease in people. ​Scientists at …
